The paper deals with the issue of capacity of railway infrastructure in connection with the operation of freight trains with a length of up to 740 m. First, the facts in the field of the arrangement of railway infrastructure elements that may have a potential impact on capacity will be listed. Subsequently, there will be proposed indicators that can be used for detection of possible changes in capacity, due to the operation of trains with a length of 740 m. In the last phase, several simulation scenarios will be realized in the OpenTrack program. In these scenarios 740 m long trains will be deployed on the selected routes of the model timetable. The simulation results will eventually be evaluated using previously proposed indicators.

This paper deals with railway lines with low traffic intensity where trains are operated under simplified conditions. Those conditions are stated in a regulation, and there is no interlocking system on the line. The whole railway operation is organized according to a regulation in cooperation with the train crew. For the calculation of the throughput, we can use analytic or simulation methods. On those lines there is a big problem with the common working methods because of special circumstances on each line, which are influencing the technological times and reliability of the calculation. The simplified conditions are the transforming of regular interlocking systems on the administrative level. Therefore, it is very complicated to use a common simulation model. Most of the simulation tools are not able to work with it. The motivation of this paper is to prove that modern simulation tools are usable for that specific condition as well. The simulation model was built in SW OpenTrack which is able to modify its functions to figure out each technological action to ensure the correct function of the model. This functionality is described in the paper in general and implemented on a case study.

The last mile is characterized as the last step of delivery to the customer from the logistics point of view. It is necessary to aim and fulfill all customers’ needs mainly during the process of the last mile, because it is directly connected to them. Customer orientation can cause many complications that must be solved according to their will. This part of the supply chain is currently under pressure. Nowadays, trends have changed the last mile into a more ecological process mostly in the transport field. Railway transport is considered as an ecological transport mode therefore the last mile should be done by the railway transport. Preconditions for doing the last mile by the railway transport is the existence of siding (special purpose tracks) at the place of delivery. Our research focuses on minimizing the negative impacts of the last mile to customers in the context of using sidings. This research is based on the real conditions of the Slovak rail network, and on consultation with some experts from freight transport companies.

Using simulation in OpenTrack, this paper analyses the journey of type trainsets on model infrastructure in the line section Rokycany–Ejpovice–Plzeň hl. n. The aim of this paper is to assess the efficiency of increasing the track speed in this section. Analyzing the output characteristics of the simulation, selected indicators were assessed which influence the efficiency of further increases in track speed. One of the simulation scenarios is using the European Train Control System Level 2 (ETCS L2) system as the necessary condition of the speed over 160 km·h−1.

In the paper, the present state of scientific knowledge in authorising the types of railway vehicles in Slovakia and abroad is analysed by the authors. The aim of the authorisation of the types of railway vehicles is to take into account the interests of the whole society in the field of transport in the manufacturing of these vehicles or their import from abroad. These interests mainly include a greater security of transport, as well as a greater quality, reliability and lifespan of railway vehicles. The authors also analyse the Commission Recommendation 2014/897/EU of 5 December 2014 on matters related to the placing in service and use of structural subsystems and vehicles under Directives 2008/57/EC and 2004/49/EC of the European Parliament and of the Council, which should contain instructions related to the matters in question. At the same time, it is necessary to take into account Directive (EU) 2016/797 of the European Parliament and of the Council of 11 May 2016 on the interoperability of the rail system within the European Union, and Directive (EU) 2016/798 of the European Parliament and of the Council of 11 May 2016 on the railway safety. In addition to ensuring the applicability of interoperability regulations (new directives, regulations, decisions, recommendations, etc.), the aim of this paper is to present a methodology of authorising the types of railway vehicles and a software model (SW) of authorising the types of railway vehicles, with European legislation as a possible tool to speed up and simplify the entire process. The paper is concluded by three types of authorisation processes for different railway vehicles and their accessories, comparing the length and complexity of processing using the standard authorisation process and using the SW tool proposed.

The gradual liberalization of the Czech rail market did not leave unaffected sidings and railway infrastructure managers operating railway transport as their main business activity at the same time. This paper presents the main changes in capacity allocation on public sidings in accordance with the amendment to the Act on Rail Systems. It outlines the specific procedures in capacity allocation on public sidings, the specific modes of request processing and the economic side of capacity allocation. The purpose of capacity allocation is to allow for an efficient use of services offered to all authorized entities. The requests are generally submitted through PROK SW. Furthermore, this paper touches on the initial experience of the Faculty of Transport Engineering of the University of Pardubice, as a capacity allocator on public sidings and rails owned by České dráhy, a.s., with statistical evaluation.

Simulation modelling is one way to determine the capacity of railway lines. The specialized software tool OpenTrack was used for simulation. The aim of this paper was to find out whether the OpenTrack simulation software can be used for the calculation of headway, and to compare the results with the methodology of the Railway Infrastructure Administration (SŽDC). Using the software tool, a detailed transport network model can be created including all its important characteristics. The simulation follows the movements and behaviour of trains with predefined parameters on the modelled railway line. OpenTrack allows for monitoring a range of parameters including not only train delays, train conflicts and train traffic flow, but also for instance train energy performance and headways. During the first stage of work with OpenTrack, a simulation model was created, not reflecting any existing infrastructure but including parameters typical of railway lines in the Czech Republic, such as the configuration of gridirons, length of station tracks, size of block sections, etc. This model was subsequently used for the simulation of type train set journeys, and a headway calculator was used for the calculation of headway values. These values were compared with the methodology used by the Railway Infrastructure Administration. The paper is concluded by the comparison of the above mentioned approaches.

Current business trends push transport companies to improve the efficiency of their entrepreneurial activities, what is closely related to costs reduction and revenues increase. Many transport companies achieve it empirically, but some mathematical algorithms, mainly from operational research, can be used to improve the efficiency of railway transport by finding the optimal solution of specific problems. The paper is focused on using of selected methods from applied mathematics in railway transport. These methods are used mainly for improving the operational efficiency of the transport company, what tends to decrease overall operating costs. Major impact is done by efficient use of railway vehicles and train staff. It can be achieved by optimization as a flow network problem or assignment problem, what is further described in the paper. Mathematical approaches can also positively influence the whole logistic process.

Integrated passenger transport system consists of many factors with various impacts on the entire system quality. In passenger transport, there are mostly individual passengers therefore it is difficult to determine all transport requirements. In the passenger transport system, there are several modes of transport, but passengers mostly use road and rail transport. Passenger transport system is influenced by many qualitative factors with various impacts. The paper is focused on analysis of the role of railways in integrated passenger transport systems. The analysis is from passenger point of view because the key element in railway passenger transport is the passenger (customer), who requires the transport from one place to another. A basic precondition for accomplishing the main requirement (transport), is making the complete offer which provides not only transport, but also other complementary services. There are several types of passenger trains, which jointly create a part of integrated transport system. Quality of this transport system depends on train route topology, timetable of trains, number and location of all stations and stops. Primary function of the transport system is providing transport for passengers on regional, national-interregional and international level; therefore, the analysis involves these levels.

This paper describes an innovative system of container reloading. The system involves Tandem spreaders included in portal cranes moving at the quay edge of maritime port container terminals. Thanks to the modern construction, it is possible to reload up to four ISO 1C containers at the same time, which not only reduces the reloading time, but also increases the reloading capacity of the terminal. The paper also discusses the economic aspects of the introduction of these new spreaders.

The paper deals with possibilities of optimizing the process of check-in and security check at airport terminals using simulation program. Proposed model is based on real parameters and simulated in the environment of the program Tecnomatix Plant Simulation. This program simulates the process of check-in and security check. Queuing theory will be used for simulation. Principally it means queuing customers, i.e. accumulation of requests, in front of a service centre. Limiting criteria for optimization include operating conditions of airport terminals, financial means connected with personnel resources, legal standards related to safety in air transport and level of service indicators. The aim of the paper is to create a model, which analyses the passenger flow processes at the airport terminal and could be used for evaluating potential changes of the check-in and security check system at airport terminals.

This article defines a new capacity parameter called capacity range (CR). The definition is explained and then the parameter is calculated for a selected section of Kolín – Choceň (overlapping section of RFC 7 and RFC 9). The calculation is based on timetable 2016. Capacity range, expressed as dependence of the number of trains on average delay increment, is a useful capacity parameter particularly for coherent railway sections with remote traffic control.
